Good water filter

Have used Zero water filter systems for many years and is one of the better filters I've used. Water taste is definitely improved

Great quality

Excellent quality and durability, It only requires change every 3 months, and it is from a brand that I trust, 3M. It provides a certain level of Air purification and help with seasonal allergies
